Hello.
Trouble to communicate with APC SmartUPS via serial port.
UPS connected to the com1 port on windows host.
Communication witch hyperterm works well.
There is a log:
YSM
^ASmart-UPS SC1000
n5S0713T63247
m03/29/07
L240.0
B27.10
apcupsd also can communicate with the UPS and works well.
running apcsmart -a ups gives the following:
com1: device reports different attributes than what were set
unable to detect an APC Smart protocol UPS on port com1
check the cabling, port name or model name and try again
All issues related to certain sanity checks (and some misbehaviour)
while setting up serial ports should be fixed in the current version of
nut. Is it possible for you to try current version of nut ?
There should be apcsmart-old present in your build as well, so if it's
not possible - you can use the previous version easily.
ups.conf:
[ups]
driver=apcsmart
port=com1
cable=940-0095B
desc="test"
Sysinternals Portmon captures the following activity on com1:
0.00009862 apcsmart.exe IRP_MJ_WRITE Serial0 SUCCESS Length 1: 59
Y
0.00001090 apcsmart.exe IRP_MJ_READ Serial0 SUCCESS Length 1: 53
S
0.00000950 apcsmart.exe IRP_MJ_READ Serial0 SUCCESS Length 3: 4D 0D
0A M [CR] [LF]
1.48775808 apcsmart.exe IRP_MJ_READ Serial0 TIMEOUT Length 0:
0.00010029 apcsmart.exe IRP_MJ_WRITE Serial0 SUCCESS Length 1: 1B
[ESC]
0.00001117 apcsmart.exe IRP_MJ_READ Serial0 SUCCESS Length 1: 4E
N
0.00000950 apcsmart.exe IRP_MJ_READ Serial0 SUCCESS Length 3: 41 0D
0A A [CR] [LF]
Thus, apcsmart sends the Escape character, which is not recognised by UPS and
returns NA.
Is there a solution for this issue?
Thank You and sorry for my English.
The actual issue above was that when setting serial port, IGNCR was
ignored and the new driver expected that to be honored. It's fixed in
the current version (CR is always filtered now), but not in that
particular build. Current driver also allows to use both canonical and
raw modes, so should the former (default) fail, the alternative is
available.
